Enumuration
Looks like you start at 211 lbs and you are trying to hit 180 lbs
Then it goes all the way up to day 7 and tells you if you reached to certain weight or not.

Looking at disassembly, goal is to get to 0xb4(180)
Activity Effects
| Activity | Effects |
|---|---|
| 1 | weight = weight – 4 |
| 2 | weight = weight – 1 |
| 3 | weight = weight – 5 |
| 4 | weight = weight – 3 |
To get to 180 lbs from 211, we need to lose 31 lbs. And we get 7 days.
If you choose Activity 3 six times Activity 2 once, we should hit 31.
